Coal dust inhibitor of rapid infiltration type and preparation method thereof

The invention discloses a coal dust inhibitor of rapid infiltration type and a preparation method thereof. The coal dust inhibitor is characterized by comprising, by weight percentage, 0.5-5 parts of PVA (polyvinyl alcohol), 0.1-5 parts of CMC (carboxymethyl cellulose), 0.3-3 parts of glycerin, 0.1-2 parts of a nonionic surfactant, and 85-99 parts of tap water. The preparation method is characterized by comprising the steps of: first completely dissolving the PVA with hot water at 90-100 DEG C, and completely dissolving the CMC with warm water at 30-40 DEG C; and then mixing the two aqueous solutions, adding the glycerin and the nonionic surfactant, and stirring. The coal dust inhibitor of rapid infiltration type provided by the present invention has no toxicity or pollution nuisance, easily available raw materials, low cost, convenience for usage and preparation, rapid penetration, fast film forming, thick and tough film, and good dust suppression effect, and can be applied to a variety of circumstances caus
